Research

I am a marine ecologist studying population and community ecology in coastal environments (coral reef, artificial reef, seagrass/macroalgal beds...etc). 

Since PhD student, I have been studying about larval dispersal of marine organisms using approaches of field survey, population genetics, and biophysical model.

Besides  these study themes, I am now interested in impacts of herbivore fishes on marine forests in template coasts of Japan under ocean warming.

サンゴ礁、人工魚礁、藻場などの沿岸生態系を対象に個体群生態学、群集生態学、生態系サービスの研究をしています。

博士課程～ポスドクのときに、集団遺伝学や野外分布調査、数値解析モデルを用いて海産魚の分散や移動を研究していました。

環境DNAを用いた人工魚礁の効果評価や、藻場の調査手法の開発、魚類の生態系サービス評価についての研究を進めています。
